Filter by:Is VAX125 safe at doses ranging from 0.1 to 8 ug when delivered i.m. in a single dose regimen Is VAX125 able to induce a post-vaccination serum HAI antibody response in healthy adults against the influenza A virus H1 HA.
The present study is intended to assess a novel formulation of FluLaval. The idea is to obtain preliminary data on the safety and immune response to the FluLaval TF influenza vaccine in adults. These data will serve as a basis for further studies involving different populations. This protocol posting deals with objectives & outcome measures of the primary phase/study.
In the 20th century, influenza pandemics occurred in 1918, 1957, and 1968, and were associated with significant morbidity and mortality. It is estimated that, in the United States alone, the next influenza pandemic could cause approximately 200,000 deaths and 750,000 hospitalizations. Thus, the development of a vaccine against potential influenza strains has become a priority. The purpose of this study is to determine the safety and immune response to an H2N2 influenza vaccine candidate.
The purpose of this study is to determine whether GSK's avian flu vaccine GSK 1557484A is immunogenic and safe when given to adults aged >=18 years. This Protocol Posting has been updated following Amendments 1-3 of the Protocol, Dec 2009. The impacted sections are study design and outcome measures.
This study is for a new marketing authorization application for the seasonal vaccine strains in compliance with the Note for Guidance (NfG) on harmonization requirements for influenza vaccine from the Committee for Human Medicinal Products (CHMP) Objectives: - To evaluate the compliance, in terms of immunogenicity, of the inactivated, split-virion influenza vaccine NH 2008-2009 formulation with the requirements of the CHMP NfG CPMP/BWP/214/96. - To describe the safety of the inactivated, split-virion influenza vaccine, NH 2008-2009 formulation.
The purpose of this study is to evaluate the safety and immunogenicity of GSK influenza vaccine candidate compared to a licensed trivalent influenza vaccine in adults.
The purpose of this study is to assess the safety and tolerability of, and the immune response to a non-adjuvanted H5N1 influenza vaccine in an adult and elderly population and in specified risk groups. Furthermore, persistence of H5N1 influenza antibodies after vaccination with this vaccine will be assessed.
The purpose of this study is to compare the antibody response and reaction rates in children age 6-23 months when they are given either the currently recommended schedule of two 0.25ml doses of influenza vaccine one month apart or two 0.5ml doses of influenza vaccine, one month apart.
The trial will enroll up to 57 subjects. Qualified normal healthy volunteers will be enrolled in the study to receive the vaccine or placebo vaccine. Subjects will receive 2 vaccinations with a needle and will be followed for 6 months to evaluate the safety of and the immune system's response to the vaccine. The safety and immune system response will be studied throughout the trial.
Background In preparation for a global influenza pandemic, there is an urgent need for representative data from populations and settings where the pandemic is most likely to arise. There are no data on oseltamivir efficacy from Asian urban slum populations concerning duration of illness and viral shedding, nor whether efficacy depends on starting treatment < 48 hours or ≥ 48 hours after illness onset. Finally, there are no data on the capacity of the drug, in such settings, to affect household and community transmission rates. Aims and Objectives This proposal aims to compare the duration of clinical illness among patients treated with oseltamivir vs placebo < 48 hours and ≥ 48 hours after illness onset. It will compare the duration of viral shedding among all treatment groups vs placebo, risk of transmission to household contacts by treatment group and whether neuraminidase inhibitor use creates resistance. Secondarily it aims to measure the effect on influenza. Design and Methods A double-blind placebo controlled clinical trial design among a population in an urban slum under current influenza disease burden surveillance will be enrolled. Infection status will be confirmed by rRT-PCR. Patients ≥ 1 year old will be randomised to < 48 hour and ≥ 48 hour treatment arms. Family members and neighbours will also be assessed by PCR and a basic reproductive number calculated (R0). Relevance These findings will address whether oseltamivir can affect illness duration and severity, affect transmission, incidence and resistance in high risk urban Asian settings where a pandemic is most likely to arise.
